Abstract

A bicycle frame has the main frame members made of folded sheet metal, with a hollow triangular cross section. The main frame comprises an upper cross bar (10) a lower frame (12), a saddle support (14) and a front wheel support (18). The frame sections are joined by their edges with additional support provided by angled strips at the joints. Additional support is provided by a second saddle support (16) secured to the main saddle support. The triangular cross section has equal sides and the assembly is via welding, screw fasteners, rivets, etc.
